17、rt of the series of EN non-metallic materials standards for aerospace applications. The general organisation of this series is described in EN 4385. This standard is a level 3 document as defined in EN 4385. 1 Scope This European Standard specifies the procedure for the determination of water extrac
18、table matter of textile material. This method has been written in response to an aerospace requirement for a method of extraction using hot water. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicatio

21、ich may be present in the fabric, i.e. yarn size, oils or grease that is extractable by boiling water 4 Health and safety This standard does not necessarily include all health and safety requirements associated with its use. Persons using this standard shall be familiar with normal laboratory/test h
22、ouse practices. It is the responsibility of the user to establish satisfactory health, safety and environment practices and to ensure conformity with any European, National or local laws/regulations. 5 Principle/Technique An aqueous extract is prepared using distilled or deionized water. The extract
23、able matter is then measured by gravimetric method. 1) Published as ASD-STAN Prestandard at the date of publication of this standard BS EN 4507:2013EN 4507:2013 (E) 5 6 Resources/Facilities 6.1 Apparatus 6.1.1 Round bottomed flasks of chemically resistant glass with a volume of 250 ml and a ground g

26、 required and shall be of recognised analytical quality. Distilled or deionized water, having a maximum conductivity of 1 mS/m 6.3 Qualification of personnel No specific requirements 7 Test samples/Test pieces Samples shall be taken representative of the bulk and of sufficient size to provide all th
27、e test specimens required. All samples shall be kept identifiable to the bulk textiles which they represent. Cut the sample under test into pieces of such size that all parts readily wet out. Care must be taken to avoid any contamination of samples and handling must be kept to an absolute minimum. N
28、OTE Nominal 10 mm squares have been found suitable. The samples are conditioned and tested in a standard atmosphere of (65 2) % r.h. and (20 2) C in accordance with EN 20139 Standard Temperate Atmosphere For Testing. BS EN 4507:2013EN 4507:2013 (E) 6 8 Test procedure 8.1 Cut the sample into nominal
29、10 mm squares and weigh (5 0,05) g of conditioned sample into flask(6.1.1). 8.2 To the flask containing the sample under test add (100 0.1) ml of distilled water (6.1.2). NOTE For sample weight of less than 5 g, the liquor ratio should be maintained at 1:20, i.e. 1 g of sample to 20 ml of water. 8.3
30、 Connect the flask containing the sample and water to the water cooled condenser (6.1.3). Quickly bring contents to the boil and continue to boil liquor gently for 60 minutes. After this period disconnect and remove flask from condenser whilst liquor is still boiling close immediately with the glass
31、 stopcock (6.1.2). 8.4 Do not filter or make up volume but cool rapidly to (20 2) C to ensure a partial vacuum is created to ensure the extract is not contaminated. 8.5 Determination of water extractable matterFilter the extract through a suitable filter paper (6.1.5) and evaporate a measured portio
32、n of the filtered extract to dryness in a tarred evaporating vessel (6.1.6). 8.6 Dry the residue at 105 C to 110 C until a constant mass is achieve (no more than 0,0005 g loss of mass on drying for a further 30 min). 9 Expression of results 9.1 Individual results Not applicable. 9.2 Calculation The
33、water extractable matter (Pw) is calculated as a percentage by mass of the conditioned mass of the specimen, by the following equation a) For yarns or fabrics other than wool Pw = Vm3102b) For felts, loose fibres and wool in any textile form Pw = Vm3105where m is the mass of the residue (g) V is the

35、 c) The content of water extractable matter as a percentage of the conditioned mass of the specimen; d) Traceability to the individual who performed the test; e) Date of test; f) Details of any deviation from this test method.
